2019-01-09misc: imx8: scu: use platdata instead of priv dataPeng Fan
priv data has not been allocated when doing bind, so it is wrong to use dev_get_priv in bind call back. Let's switch to use platdata in the driver to fix the issue. Signed-off-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2019-01-09misc: imx: scu: avoid write null pointerPeng Fan
When boot_dev is true, fill boot device. However the original logic is when boot_dev is false, fill boot device, this will trigger data abort. Also fix sc_misc_get_control when using pointer val. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2018-11-14dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in lists_bind_fdt()Bin Meng
Currently the comments of several APIs (eg: dm_init_and_scan()) say: @pre_reloc_only: If true, bind only drivers with the DM_FLAG_PRE_RELOC flag. If false bind all drivers. The 'Pre-Relocation Support' chapter in doc/driver-model/README.txt documents the same that both device tree properties and driver flag are supported. However the implementation only checks these special device tree properties without checking the driver flag at all. This updates lists_bind_fdt() to consider both scenarios.
